Great! Now adding "Run away neutron star" to the list of things that could pretty much literally hurl out of space and kill us all....

/With no knowledge to back it up other than what I know about gravity the damn thing would probably just need to pass within the orbit of Pluto to fling us off into space....or kill us with x-rays..... or cause so many objects to leave the Kuiper belt that we'd be smashed in the ensuing shotgun blast of comets....

First of all, we all know from the remastered and perfected Episode IV, any large body that explodes in space eminates a perfect ring of energy from a smaller sparkley explosion.Secondly, +1 to The Bad Astronomer for a neat link. -1 to aforementioned for inappropriate summoning.

Not likely.

We'd see it coming just for sake of how we discovered it from the article. The superheated gas it emitted would give us indications it was coming tens of thousands of years before it even had a chance to hurt us.

What would more likely what would happen is Earth would be showered with comets from the oort cloud if something like that came our way. Gravity is far too weak of a force to affect a planet our size from that distance away.
